Permissible motor cable lengths for SINAMICS G150
When two motor reactors are connected in series, the permissible cable lengths can be increased even further to
450 m with shielded cables and 675 m with unshielded cables. For SINAMICS G150 parallel converters with power
outputs ranging from 1750 kW to 2700 kW, the following values apply in the case of two motor reactors:
525 m for shielded cables and 787 m for unshielded cables.
A second motor reactor is not a standard option and may require an additional cabinet. A second motor reactor is
therefore available only on request.
5.9 SINAMICS G150 parallel converters (SINAMICS G150 power extension)
SINAMICS G150 cabinet units in the high output power range are designed as parallel converters. Their design is
based on either two lower-output SINAMICS G150 converter cabinet units or on two Basic Line Modules and two or
three Motor Modules.
Due to the design principle applied, each of the following components is used more than once in the configuration:
· Line supply connections
· Main contactors or circuit breakers
· Power unit components
· Motor connections
A parallel connection features only one each of the following:
· CU320-2 Control Unit
· AOP30 operator panel
· Optional customer interfaces TM31 (option G60 or G61) or TB30 (option G62) with digital and analog
inputs and outputs
The following overview shows the three design variants of SINAMICS G150 parallel converters.
